Product overview
be quiet lists BK042 as a pure rock pro 3 black 120mm rifle cooling fan. Airflow direction has to match the aisle, and a fan module with the wrong orientation will fight the rest of the row. Tell us the rack layout and we will confirm the part.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

What you get ordering this from us
Ordered by part number
Quoted and supplied against BK042 specifically, so what arrives is what your build sheet asks for.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Airflow direction confirmed
The module is checked against the aisle layout so it works with the row rather than against it.
Questions buyers ask about this part
Is BK042 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will BK042 work in my server?
Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it: firmware revision and platform generation matter, and this is the check that prevents a return.
Do you accept purchase orders and quote at volume?
Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.
